//created by RunTime Technologies
//--- added match variable to match 2 (or more) form elements
//modified 9/24/1999
//--- added requirement checking for radio,selects,checkboxes
//--- added legal check type to block illegal chars in a text string
//modified 1-31-2002 -- localize all messages, Bob Matsuoka;
//modified 8-23-2002 -- add isOneChecked logic and function, Jon Gill;
//mod 9-20-2002 -- option to submit even on already submitted, Bob M;
//mod 10-11-2002 -- checkAll now looks for either the presense of a message or a "check" type -- specifically useful for makeLegal, which returns its own separate message;
//mod 11-1-2002 -- isEmail now checks for the presence of a '.', but does not require that it's after the 3rd character, i.e., jw.family@buddy.sohonet.com was failing check
//mod 11-6-2002 -- fixed syntax errors in isLegal, Jon Gill;
